Problem: Functions used in one file are global.
Solution: Add "static". (Yegappan Lakshmanan, closesvim/vim#4840)

Problem: too many strlen() calls in drawscreen.c
Solution: refactor drawscreen.c and remove calls to strlen(),
make get_keymap_str() (in screen.c) return string length
instead of TRUE/FALSE (John Marriott).

Problem: Message grid newline formatting based on `msg_col` is not
utilized with ext_messages.
Solution: Increment `msg_col` with the cell width of the chunk. Allowing
message code that uses `msg_col` to determine when to place a
newline to do so. E.g. when the message goes beyond `Columns`;
this is not necessarily where the ext_messages implementation
would want to place a newline, but it is a best guess. Message
parsing and manipulation is still possible.
Problem: Highlight group id is not propagated to the end of the message call
stack, where ext_messages are emitted.
Solution: Refactor message functions to pass along highlight group id
instead of attr id.
Use the grapheme break algorithm from utf8proc to support grapheme
clusters from recent unicode versions.
Handle variant selector VS16 turning some codepoints into double-width
emoji. This means we need to use ptr2cells rather than char2cells when
possible.
Problem: POSIX function name in exarg struct causes issues
on OpenVMS
Solution: Rename getline member in exarg struct to ea_getline,
remove isinf() workaround for VMS
There are compilers that do not treat well POSIX functions - like
getline - usage in the structs.
Older VMS compilers could digest this... but the newer OpenVMS compilers
( like VSI C x86-64 X7.4-843 (GEM 50XB9) ) cannot deal with these
structs. This could be limited to getline() that is defined via
getdelim() and might not affect all POSIX functions in general - but
avoiding POSIX function names usage in the structs is a "safe side"
practice without compromising the functionality or the code readability.
The previous OpenVMS X86 port used a workaround limiting the compiler
capabilities using __CRTL_VER_OVERRIDE=80400000
In order to make the OpenVMS port future proof, this pull request
proposes a possible solution.

Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
Problem: buffer text with composing chars are converted from UTF-8
to an array of up to seven UTF-32 values and then converted back
to UTF-8 strings.
Solution: Convert buffer text directly to UTF-8 based schar_T values.
The limit of the text size is now in schar_T bytes, which is currently
31+1 but easily could be raised as it no longer multiplies the size
of the entire screen grid when not used, the full size is only required
for temporary scratch buffers.
Also does some general cleanup to win_line text handling, which was
unnecessarily complicated due to multibyte rendering being an "opt-in"
feature long ago. Nowadays, a char is just a char, regardless if it consists
of one ASCII byte or multiple bytes.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
Problem: no digraph for quadruple prime
Solution: add quadruple prime digraph using 4'

- Move vimoption_T to option.h
- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h
- option_defs.h and option_vars.h don't include each other
Problem: Vim9: leaking memory when using continuation line.
Solution: Keep a pointer to the continuation line in evalarg_T. Centralize
checking for a next command.

drawscreen.c vs screen.c makes absolutely no sense.
The screen exists only to draw upon it, therefore helper functions
are distributed randomly between screen.c and the file that
does the redrawing. In addition screen.c does a lot of drawing on the
screen.
It made more sense for vim/vim as our grid.c is their screen.c
Not sure if we want to dump all the code for option chars into
optionstr.c, so keep these in a optionchar.c for now.
Problem: Code is indented more than necessary.
Solution: Use an early return where it makes sense. (Yegappan Lakshmanan,

Partial port as some highlight.c changes depend on previous patches.
Cherry-pick fname_match() change from patch 8.2.4959.
Omit internal_func_check_arg_types(): only used for Vim9 script.

vim-patch:9.0.1167: EditorConfig files do not have their own filetype
Problem: EditorConfig files do not have their own filetype.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)

This is an approximation vim-patch 8.1.2057. Applying the patch directly
isn't feasible since our version of screen.c has diverged too much,
however we still introduce drawscreen.c and drawline.c:
- screen.c is now a much smaller file used for low level screen functions
- drawline.c contains everything needed for win_line()
- drawscreen.c contains everything needed for update_screen()

Problem: Default cmdwin mappings are re-mappable.
Solution: Make the default mappings not re-mappable. (closesvim/vim#10580) Use
symbols for the first do_map() argument.
